The average blood pressure for adults in the 30-40 year old age range is about 135. A researcher wonders whether the blood pressure of individuals with high stress positions differs from 135, keeping age range constant.
For a random sample of 120 people with high stress jobs, he
found:
X_bar = 137
p-value = 0.11
95% CI (139 to 141)
Based on these findings, he decided not to reject the null. Did he make the right decision?
Select one:
a. The results reported by this researcher are inconsistent and contradictory.
b. Yes, he made the right decision becasue the probability of rejecting the true null is 11%, and it is higher than the 5%.
c. This researcher needs to report the standard deviation for his data.
d. He did not make the right decision because his confidence interval does not include the hypothesized value under the null.
